(54)	TRICUSPID REGURGITATION TREATMENT TOOL TO BE INSERTED INTO PULMONARY ARTERY

(57) A tricuspid regurgitation treatment tool to be inserted into the pulmonary artery is proposed. The tricuspid regurgitation treatment tool to be inserted into the pulmonary artery is used to verify whether the right ventricular dysfunction may occur when treating the tricuspid regurgitation by surgeries or other permanent treatments. A test insertion of the tricuspid regurgitation treatment tool to be inserted into the pulmonary artery is made to pass obliquely through the tricuspid valve of a patient, and after a certain time has elapsed, the tool is removed. The tricuspid regurgitation treatment tool to be inserted into the pulmonary artery includes: a blocking part blocking the tricuspid valve; and an insertion tube provided with a guidewire-guiding lumen formed therein to be movable along the guidewire.
